Description
Technical field
This utility model relates to a kind of dental handpiece hermetically-sealed construction.
Background technology
Be provided with the pipe of conveying steam and air-flow in current dental handpiece on the market, but the connection sealing effectiveness of pipe and dental handpiece body is bad, currently available technology adopts gluing sealing.But when carrying swiftly flowing air-flow, gluing mode being easy to gas leakage, easily causing in dry solidification process inconsistent because of different parts state of cure due to the characteristic of glue itself in process of production in addition thus causing product to leak gas.
Summary of the invention
In order to overcome dental handpiece inside tube and dental handpiece body connecting portion sealing effectiveness is poor, easily cause the deficiency of leaking gas, this utility model provides a kind of dental handpiece hermetically-sealed construction.
The technical scheme in the invention for solving the technical problem is: a kind of dental handpiece hermetically-sealed construction, comprise handle main body and be assemblied in the connector of described handle main body rear end, described handle main body rear end is provided with carrier pipe, also comprise a rubber sealing block, through hole is provided with in the middle part of described rubber sealing block, described rubber sealing block is set on described carrier pipe by described through hole, be provided with the seal groove of setting described rubber sealing block in described connector, described rubber seal block length is greater than the described seal groove degree of depth.
Further, for preventing gas backstreaming, the through hole back-end face on described rubber sealing block is extended with sheet rubber.
Further, described connector rear end is provided with air inlet pipe, escape pipe, air jet pipe, sparge pipe, side, described connector rear end is also provided with screw thread, described connector front end face is provided with the container cavity of setting handle main body rear end, described seal groove is arranged on bottom described container cavity, described seal groove and described air inlet pipe, air jet pipe, sparge pipe UNICOM;
Described carrier pipe comprises appendix, vapour pipe, through hole on described rubber sealing block comprises the first through hole passed for appendix and the second through hole passed for water air pipe, described sheet rubber is arranged in described first through hole, and described rubber sealing block is set on described appendix and vapour pipe.
Further, for convenience of fixing and place connector and dental handpiece handle portion relatively rotates, appendix and vapour pipe is caused to bend, also stopper slot is provided with bottom described container cavity, described stopper slot and described escape pipe UNICOM, described handle main body rear end is also provided with gas outlet, and limit, described gas outlet is provided with the spacing block set be embedded in described stopper slot.
Further, for saving cost, described appendix and vapour pipe adopt plastic tube.
Further, described handle main body and connector adopt gluing fixing.
This utility model is when assembling, handle main body and connector are fixed, because rubber seal block length is greater than described seal groove, rubber sealing block by bottom seal groove with the crimp of handle main body rear end face, expand to surrounding, after expanding, rubber sealing block and groove side wall fit tightly, thus play good sealing function.
The beneficial effects of the utility model are: good sealing effect, and solution carrier pipe and dental handpiece body seal the technical barrier of difference, have the function of anti-return.
Accompanying drawing explanation
Fig. 1 is that this utility model handle is separated schematic diagram with connector.
Fig. 2 is this utility model connector internal structure schematic diagram.
Fig. 3 is that this utility model rubber sealing block is separated schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figures 1 to 3: a kind of dental handpiece hermetically-sealed construction, comprise handle main body 1 and be assemblied in the connector 2 of described handle main body 1 rear end, described handle main body 1 rear end is provided with carrier pipe 3, also comprise a rubber sealing block 4, through hole 5 is provided with in the middle part of described rubber sealing block 4, described rubber sealing block 4 is set on described carrier pipe 3 by described through hole 5, is provided with the seal groove 6 of setting described rubber sealing block 4 in described connector 2, and described rubber sealing block 4 length is greater than described seal groove 6 degree of depth.
In the present embodiment, for preventing gas backstreaming, the through hole back-end face on described rubber sealing block is extended with sheet rubber 7.
In the present embodiment, described connector 2 rear end is provided with air inlet pipe 2-1, escape pipe 2-2, air jet pipe 2-3, sparge pipe 2-4, side, described connector 2 rear end is also provided with screw thread 2-5, described connector 2 front end face is provided with the container cavity 2-6 setting handle main body rear end, described seal groove 6 is arranged on bottom described container cavity 2-6, described seal groove 6 and described air inlet pipe 2-1, air jet pipe 2-3, sparge pipe 2-4 UNICOM;
Described carrier pipe 3 comprises appendix 3-1, vapour pipe 3-2, through hole 5 on described rubber sealing block 4 comprises the first through hole 5-1 passed for appendix and the second through hole 5-2 passed for water air pipe, described sheet rubber 7 is arranged in described first through hole 5-1, and described rubber sealing block cover 4 is located on described appendix 3-1 and vapour pipe 3-2.
In the present embodiment, for convenience of fixing and place connector and dental handpiece handle portion relatively rotates, appendix and vapour pipe is caused to bend, stopper slot 2-7 is also provided with bottom described container cavity, described stopper slot 2-7 and described escape pipe UNICOM, described handle main body 1 rear end is also provided with gas outlet 8, and limit, described gas outlet 8 is provided with the spacing block set 9 be embedded in described stopper slot 2-7.
In the present embodiment, for saving cost, described appendix and vapour pipe adopt plastic tube.
In the present embodiment, described handle main body and connector adopt gluing fixing.
